Product Overview

The Westlake Pipe & Fittings KIT80601S 8" Wafer Check Valve Contractor Kit provides a complete solution for installing a compact non-return valve in commercial pool, spa, and compatible water-handling piping systems.

This contractor kit combines an 8" 601N Series PVC/EPDM wafer check valve, two PVC Van Stone loose-ring flanges, and a properly sized 304 stainless steel bolt set under one convenient part number. The compact wafer-style valve installs between compatible flanges and requires less piping space than many conventional check valve designs.

An integrated 316 stainless steel spring helps control opening and closing action, reducing water hammer while providing dependable backflow prevention.

Specifications

Installation Information

The wafer check valve installs between compatible flanges. When installed using appropriate ANSI Schedule 80 flanges and piping, the valve disc can open fully without requiring additional spacers.

Stainless steel bolt and nut threads should be properly lubricated with an appropriate anti-seize compound before installation to help prevent galling.

Installation should follow all applicable plumbing requirements and Westlake Pipe & Fittings installation instructions.
